One angle of an isosceles triangle measures 50º. Which other angles could be in that
isosceles triangle? Choose all that apply.

50° , 80°, 65°

the sum of the angles in a triangle is 180°

=>180-50=130

def: in an isosceles triangle two angles measure the same

case 1: if two angles measure 50°

180-2*50=80

=> angles: 50, 80

case 2: if the other 2 angles measure the same

(180-50)/2=130/2=65

=> angle: 65

answer: 25.4 units

step-by-step explanation: radius = 12.7 units

diameter = twice the radius

diameter = 12.7 x 2

= 25.4
